I run 5lbs so a 2 bar would work for me. It just comes with a 4 bar. Im not sure you could build a 22re with more then 30 lbs. And even then you will have 15k plus in the motor. You would be better off swapping.  Yhe other problem with having such huge boost is turbo lag. For offroading. You would never get enough boost. Maybe if you were mud running or something or drag racing.
